Patent abstract
When information is recorded on an optical disc of DVD+R type, a latest RSAT is recorded upon completion of recording of one title. When recording of the latest RSAT fails, previous RSAT address information that indicates an address in which a previous RSAT is recorded is stored in a lead-in area of the optical disc. When an optical disc is loaded for reproduction, it is checked if the previous RSAT address information is present in the lead-in area. If it is present, the previous RSAT address information is obtained. If the latest RSAT is not found in a predetermined location but the previous RSAT address information is present, reproduction from the optical disc of DVD+R type is started by using the previous RSAT.
